Android 4.0+讀取發送彩信的APN錯誤

Question

java.lang.SecurityException: No permission to write APN settings: Neither user 10099 nor current process has android.permission.WRITE_APN_SETTINGS. 

編譯發送彩信代碼時出現此錯誤的原因是什麼？爲什麼我無法在Android 4.0及更高版本中閱讀APN？

Answer 1

我直接複製了CommonsWare給出的here的答案。

這似乎是一個有意的改變。該git commit where they added this defense包括以下注釋：

Since the DB may contain corp passwords, we should secure it. Using the same permission as writing to the DB as the read is potentially as damaging as a write. 

可以想象的是，您的問題將導致他們考慮增加一個獨立的讀取權限，但至少從目前來看，這是4.2的迴歸。
